Reaktionsschritte

To a solution of 50.3 mg (0.10 mmole) of N-[4-(3-aminopropyl)aminobutyl]-2-(7-guanidino-2-heptenamido)-2-hydroxyethanamide trihydrochloride in 1 ml of anhydrous methanol was added 0.1 ml of 2N hydrogen chloride-methanol. The mixture was stirred overnight at room temperature and the reaction mixture was concentrated under reduced pressure. The residue was purified in a manner similar to that in Example 7 using CM-Sephadex® C-25 (Na-type) and Sephadex® LH-20 to obtain 37.2 mg (72.4% yield) of N-[4-(3-aminopropyl)aminobutyl]-2-(7-guanidino-2-heptenamido)-2-methoxyethanamide trihydrochloride.
